Freely pivot-ed by an elongated huh l? to each vertical stud lat; is an upwardly inclined ontringer arm ll of T-or angle cross section, :l'ashioncd at its outer end to all'ord a seat all) which is adapted to have an article-carrying board 35 removahly attached thereto, as by set screws 50. "l he hoards 35 may he attached to a seat that is pivotally connected to the extremity of the arms l8, so that hoardcal hose can he examined on either side with :t'acility. It is to he here noted that each artitale-carrying hoard 35 is disposed at: a slight inclination over troin the vertical; preterahly-thoucli not essentially-at an angle of ten degrees, to aid the operative in hoarding the wet; article thereon.

integral with each huh -:l-i'-as host shown in Fig. ll,lare a series oi? laterally project inp' upper lugs or lingers til, 52, 53 and 541; and a pair o l lower teeth 55 5t), it: hcing noteworthy that the respective :iaerics are in parallel planes, while the purpose and :l'unction of each individual linger or tooth will be hereafter fully explaii'ied.

The means tor rotating the planetary disc or spider lit} to eli'cct. progression oil the artide-carrying hoards 35 intermittently through the enclo:-;u1e 7. comprises a toothed wheel 57 rip-idly secured at the lower end oi. the hereinhelore relin'rin'l to huh =12. This toothed wheel 57 is adapted for intern'iittent-or step by step-niovement by means of a vertical pin 58 on a. horizontally rotatable worni wheel 59 journalled to a suitable hearing (:0 securely mounted on one (it the transverse ties to. This worm wheel 5!) meshes with a worm (31 on a transverse shaft (32 journalled in hearings (i3, and adapted to be driven at ditl'erent speeds through the instrumentality oit a stepped pulley til, from any convenient source of power--not shown.

'l.o prevent haclr n'iol'ion oi the planetary disc or spider St and to hold the same in proper position while stripping and boarding, we make use ot, a graxvityatall dog or pawl (35 adapted to engage the toothed wheel and hold same stationary during; the intervals when the vertical pin 5b is disencaged therelroi'n. It will, o'l (.roursje, be. readily understood that; the dog or pawl (55 is conveniently pivoted to a lag tilt secured to the enclosure bottom it. and that said dog or pawl may he arranged in the path ol and raised hy-the pin fit} in accoriilance with conventional practice. where such devices are employed.

In order to etliect egress and ingress of the article-earrying boards 35 from and into, the drying enclosure 7', as well as attording means {0 maintaining the same relatively stationary during iroglession thcrctlirough we employ an annular ring (57 (Fig. I) o'l angle cross-section to atl'ord a transverse flange 68 whereby it is attached to the hot;- toin fl-lof the drying (BllCltl-illlC '2"; and a vertical flange tit), :iunctional as a guide rail, and so designated hereafter. As best: appreciated tlroni li ies.

the outrigger arms 48 normally engaging the' gui d'e rail '69,- ex'ceptasflhereatter' ;explained. It is also to be observed, that the annular ring 67- ,does not completely surround the disc or spider 36, but that it is segment-ally interrupted between the points 7 O, 'lementally curved cam sector'72. a v Referring more particularlyto Figs}, Ill and IV, it-Will be seen that the cam sector 72 While conforming generally'to the curvature of the annular ring 67 is fashionedtoaflord 7 3,-having an obstruction an upset bumper 74 integral "therewith,

or lateral projection and a series of insets75, 76- and 77. 111

spaced relation wlth the cam sector 72 it will be seen, we provide'the hereinbetore referred to'bearing bracket 22' with a vertical flange 7 8 Fig'. Ill -affording a succession of caI'n-paths-79,,80 and 81 in'r'adially increas ing stepped relation. The aforesaid lateral projection 74:,in conjunction with the campaths 79, and 81, are-successively effective to swing each outrigger arm 48, about its pivot stud44, to present theattached (article-carrying board: 35, exteriorly of the drying enclosure 7, for stripping and reboarding with a fresh article to be dried, as well as returning said boardin'to thedrying enclosure 7'. a

Assuming the drying machine is-as illustratedadapted for drying hosiery, and that the planetary'disc' 'orspider 36, rotates-in a counter-clockwise direction, it will be best 7 understood from Figs. I and III, that as said disc or spi'deris progressed with an'intermittent motionhereinbetore set forth-:- all of the artic1e carrying boards 35 will be passed throughfthe drying enclosure 7, in relatively stationary relation, by virtue of the teeth, 55, 56-; integral with each outrigger hub 47, engaging and being" moved stepby-step over the inner face of the guide rail said-during its entire progression there- ,througli. Such position, both as regards the board 35 as well-as its associated turning means, is dGSIgDEItBClOIl the drawings by the letter a. When an article-"carrying board "35 approaches the verticalegress "opening 82* the fact that they do not turn with respect to each other 'duringprm encounter the end 8-3" ott'he upset bumper 73 and swingthe arfireti about its pivot stud M with" aclockwise motion from theposition i designated a" to: the: 'dot-and-dash; line I inter- III,

will be laterally swung from the stripper station 5 to that designated 0 through -i1n= pact ot-the'finger 52 with the forward end of the vertical flange 78 on the bearing bracket 22, and partial cooperation with the cam path 79in a counterclockwise manner as clearly appreciable tromFig. III. The

succeeding intermittent movement of the planetarydisc or spider 36- swings the stripped'board35 to the position designated d consequent upon the'finger 52 completing traverse of the-cam-path 79: and partial counterclockwise movement over the campath 80, as best understood from Figs. I and III}, where'it is-ag'ain clothed with a wet article by th'eoperative in the well-known Way. The following intermittent movement otthe planetary disc or spider 36 transfers the reclothed' board 35 "to the position marked 6, asa result of "the lug or finger 53,

striking-and movingon to the cam-path 81 lIHl lvith" a fur'ther' counter-clockwise act-ion. At

thispoint, attention is directedto the fact that the sequence of operative movements just described-have resulted in independent motions being imparted to the outrigger arm 4'8,-concurrent w1th each successive progressive part rotation of the planetary disc or spider- 3'6. 7 Consequently; the article-carrying'board'85 has been swung out of the drying enclosure 7 through the egressop'ening 82, and back again into said enclosure by way of the ingress opening 8i intermediate the battle 27"and adjacent convergent panel 11. The succeeding movement imparted to the disc or- -spider 36 completes transfer of the article-carrying board 35 into drying enclosure traversing location a by re-engagement of the hereinbefore described lower teeth 55, 56 with the guide rail '69. Incidentally it is Worthy of "note that the insets 'or cut-awaypart-s 75', 7 6, in the cam sectoror bumper TQatfOrdc learance for-the teeth 55,

56, during the turning motions imparted to tho outrigger arms lb, whereas the inset 77 is additionally :lunctional in ensuring proper reengagcmcnt of said teeth with the guide rail till, whereby the boards are retained relatively stationary during transit through the enclosure 7. .larticular attention is directed to the tactthat the lugs or lingers til-Ell impart what we conveniently term quadriinactiona1. trips or movements to the outrigger arms ib, whereas the lower c0- planer teeth 55, so solely serve to maintain said arms relatively stationary during progression through the drying enclosure t by sliding eiigageinent with the guide rail (59.

An exhaust outlet or outlets 85, is or are, provided at suitable locations in the root ot the drying enclosure 7 for the expulsion oi excessive moisture-laden air; while closure strips ll 11 may be attached to the panels ll, ll 1 and conil'orm in outline generally with the outer edge of the boards to prevent unnecessary wastage of the drying medium.

in the term of our invention thus :t'ully dr-scrilaul, it will be observable that the phmetary disc or spider 236 and associated guide rail (it) are mainly located within the drying enclosure 7, but there may be occasions where it is preterable that said parts shall be exterior thereto. Such a contingency is provided for by the modified assemblage :tragmcntarily shown by Fig. V, wheremi all parts corresponding with the preceding detailed description are distinguished by similar reference characters. .l-lowever, it is particularly to he observed that the planetary disc or spider 3G, guide rail (it), and bumper sector 7:2 are all located below the drying enclosure bottom 14%, the same being provided with an annular opening 86 through which the article-carrying heard 35 progressed in the manner hereinhelhre set forth. Provision, however is made for substantial closure of the opening 86 by titling each arm l8 with a lateral sheet material attachment 8T oi appropriate ronl'iguratitm that lills in. the interspaccs between the successive hoards when in drying enclosure progressing position. This closure leature, it is to be understood, we lay no claim to per se, and it is only referred to :l'or the purpose oil. clarityiug apossible n1iscmu'reption easily associable with the modilied term of our invention under descriptiou.

.Should it be deemed desirable that the during medium be circulated downwardly through the drying enclosure 7 and upwardly through the hanks of heating coils 20; or vice versa, said enclosure may be provided with a perforate suh-iloor or bottom Stl-liig. VI(wholly or in part) whereby circulation can take place as directionally indicated by the arrows thereon. Further.- more, the closure elements 87 may be provided, as shown, or omitted without matorially ailecting the ei'liciency of this tornr 7 nnhlage and detail l ig .l-lV, hence corresponding reiterence cliarmtters are applied. thereto, and "lfurthcr explanation dispensed with to avoid tantalogical repetition.

One feature and ztdvimtage noticeable as consctpient upon our .novel design of drying machine is that one operative alone is ableto attend to the sti'hpping and boarding? with ease, whereby the expense of operation considerably reduced as compared with the ne'uiling practice.

From the 'l'oregoing description, the atlvautag s, simplicity and uselulncss of our novel drying machine should be thoroughly understood without :lurther explanation; and, although we have described practical embodiments thereof somewhat minutely, it is to be explicitly and atood that the some is not limited thereby, Further than as indirated in the sulrjointal claims; for the obvious reason our said invention is capable ol considerable structural Variation and other usages. without departure from its scope or sacrificing any of the :ulmntages specifically enumerated hereinabove.
